"There are dozens if not hundreds of social applications on the web. All of them want your time, and most of them want you to help them grow by referring your friends. But why should you? The only people who benefit when those apps grow are the founders and their investors. They stand to make hundreds of millions of dollars each if their product takes off, so it's no wonder they keep pressuring you to help them grow.
At Zurker, you are a co-owner and an investor. You can earn vShares by referring your friends. The more friends you invite, the more equity you earn. Zurker becomes better, and better, as more people join, increasing in value. As Zurker becomes more valuable, your stake becomes more valuable."
